Baseline revisions

For various reasons, some of the Healthy People 2010 baseline data
published in November 2000 in
Healthy People 2010:
Objectives for Improving Health, have been
revised. There were six possible reasons for NCHS to make changes to
previously published baseline figures.

Revised methodology: Modifications to the specific algorithms used to
generate the baseline data were necessary for some objectives.

Updated to objective baseline year: Data for demographic groups in the
data templates for population-based objectives that were from an earlier
year than the baseline for the main objective have been updated to the
same data year as the main objective.

Data previously not analyzed: The data templates for some
population-based objectives did not contain data for the some of the
subpopulation categories although the data had been collected. The data
have now been analyzed and the designations of "DNA" (for "data not
analyzed") have been replaced.

Data entry error: Data for a few objectives were changed because the
original figures were transcribed incorrectly from the source
documents.

Published based on preliminary analysis: Baseline figures based on
preliminary analysis from less-than-final data files have been updated
using the final data files.

New data source: Potential sources for developmental objectives were
updated to reflect more current information.

A listing of cumulative changes to the published baselines made since the
November 2000 publication of Healthy People 2010 is available.
